I need to run a node script inside my Laravel application.
I've tried using the Symfony Process, but it kill the process after the PHP execution and I need to keep the node process running, so my next step was try to use the shell_exec and exec functions. It's worked nice in the tinker and in Tinkerwell, but when I try to use inside the Laravel class it gives the following error 500:
production.ERROR: Call to undefined function shell_exec() {"exception":"[object] (Error(code: 0): Call to undefined function shell_exec() at ...
As it is a VPS I set my php.ini to disable_functions= but it still not working inside Laravel, only if I use it outside the framework.
Thanks in advance and sorry for my bad English.
Unfortunately this can't be done with exec() (nor system() or shell_exec()).
But if you install the pcntl extension, define something like:
<?php
function detached_exec($cmd) {
$pid = pcntl_fork();
if ($pid == 0) {
// Childe process main-loop goes here.
posix_setsid();
exec($cmd);
exit(0);
} else if ($pid == -1) {
// Process fork failed.
return FALSE;
}
return $pid;
}
And use like:
// Edit this:
$cmd = 'node --version';
$pid = detached_exec($cmd);
if($pid === FALSE) {
echo 'exec failed';
}
I ended giving up. I've developed an workaround.
Instead calling the node file by PHP, I made a node script whit express who receives a POST request and start the code.
Now I can put my node code in another server and it will keep running with no problems and make my system scalable.
